Gavin Rossdale spent so much time in the studio that he ''wasn't looking after his kids''.

The Bush frontman - who has Kingston, 10, Zuma, eight, and Apollo, two, with his ex-wife Gwen Stefani and Daisy, 28, from his previous relationship with Pearl Lowe - was so focused on producing music that he admits he didn't spend enough time with his youngest children.

He told the Daily Star on Sunday newspaper: ''I went into my own studio every day that I wasn't looking after my kids and it morphed into being an album.

''I still feel like I'm growing as an artist and I wanted to make a record I love myself, and that's what I have done.''

Meanwhile, the 51-year-old musician previously admitted his divorce from Gwen was one of the ''most painful things to go through''.

He shared: ''Divorce was completely opposite to what I wanted. Really not ... But here we are. Apart from death, I think divorce is one of the hardest, most painful things to go through.

''The one thing - the only good thing, because everything else is not good - is we care about the children and it's about them. So we do everything to make this life change as seamless as possible.

''It was shocking for everyone. For me, it was about being solid for them, and silent but respectful of Gwen. That's what I'll be forever. Those days were the worst days ever. It's all a bit of a blur.

''You have to try and be as compassionate as possible. It was weird because I had to go and make a home from scratch that could compare to the great one they already have. That was the challenge for me as a dad.''
